To au whom t may oon/cern:

Be it known that I, HENRY H. BAL'rzLEY, a citizenI of the United States, residing at Assumption, in the county of Christian and State of illinois, have invented certain new and useful Improvements in Hot-Air Attachments for Heating-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others Askilled in the art to which it appertains to make and use the same.

This invention aims at economy in the consumption of fuel for heating purposes and'toutilize a maximum percentage ofthe evolved heat from a given quantity of fuel for effective heating.

The device is intended for use in connection with any form of stove having an opening in its top in which it can be suspended, the lower end of the device terminating a sufcient distance from the fire to avoid being burned and from the feed-door opening, so as not to obstruct the free access to the stove for replenishing the fire, stirring the' fuel, or like purpose.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and the drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure lis a sectional detail of a stove, showing the heating attachment in position. Fig. 2 is a perspective view of the device. Fig. 3 is a perspective view of the vlower section of the Fig. 4 is a view of the uppersection inverted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The invention may be characterized as a heating attachment; and it consists, essentially, of a hollow body adapted to be suspended in the stove-top opening and having its lower end closed and provided with airducts at its sidesopening at their lower ends-il A in the lower portion of the body and at their upper ends erterior to said body and at a point above the top of the stove and below theupper vend of the said body.

The body lmay be of any cross-sectional outline and of any diameter and length and asshown is of circular form in horizontal section and is `closed at its bottom land open at the top. This body l is adapted tobe suspended in the opening in the top cfa heating-stove 2 in such a manner as to have a portion,as 3, projecting above the top of the l The portion 3, projecting above the top of the stove, may be suitably ornamented or ernbellished, so as to provide a pleasing and finished appearance. l

The ducts 5 are located at the sides of the body and interior thereof and their lower ends extend to within a short distance of the bottom of the body and their upper ends com' y municate with the external air at a point above the top of the stove and at a distance from the top edge of the part 3. These ducts may be provided in any desired number and may* have any capacity best adapted to the size of the attachment and the work required thereof. While the ducts may be formed in any way found most advantageous, it is preferred to construct theln of strips which are deiiected intermediate of their longitudinal edges, the latter constituting iianges which are bolted or otherwise secured to the inner wall of the body.

In the practical construction of the device it has been found most advantageous to construct the same of two sections detachably fitted by means of a slip-joint, the lower sec- IOO tion 6 having the outer Flange 4 formed at its upper end land provided upon its inner side with the ducts 5. The part 3 constitutes the uppersection and is indented at its lower end, as shown at '7, at points corresponding with the upper ends of the ducts 5, so as to receive said ends when the sections 3 and G are fitted together. The sections may be either cast or struck up from sheet metal, and in some instances it is preferred to have the part (i composed of halves or sections which are secured together, the strips 8, constituting the ducts 5, serving as means to overlap the side joints and to secure the sections or parts together. Y

XVhen the attachment is applied to a heating-stove, the lid or cover is removed and the attachment is suspended in the opening by means of the outer flange 4 resting in the rabbet surrounding the opening from which the lid or cover has been removed. Vhen the iire is started, the air contained in the,

body is heated and rising creates a partial vacuum in the bottom portion of the body and cold air rushes into the ducts 5 and is in turn heated and escapes from the top of the body. The circulation of air thus established is maintained so long as there is any lire in the stove. For heating a room or apartment other than that in which the stove is located it is only necessary to attach a pipe to the upper portion of the body l, when the hot air will pass to said room through the pipe as a conductor.

The h eating attachment will vbe constructed in diierent sizes, so as to iit openings oli' different diameters, and will be cast or formed of sheet metal, and in some instances will be formed of a single piece, the manner of construction being immaterial within the purview of the invention.

Having thus described the invention, what is claimed as new isl. The herein described heating attachment for stoves, comprising a lower section closed at its bottom and having an outer Ilange at its top edge, an upper section Iittcd snugly at its lower end in the upper end of said lower section, and vertical longitudinal air ducts or passages arranged in the lower section and formed independently of said upper section, and having their lower ends terminating adjacent to the betteln of the lower section and their upper ends terminating exterior to the top section, substantially as described.

2. Aheating attachment comprisingalower section closed at its bottom and having ducts upon its inner side terminating at their lower ends a short distance from the bottom, and

'an upper section fitted by a slip-joint to the lower section and having indentations to receive the upper ends of the aforesaid ducts and constituting inlets therefor, substantially as set forth.

3. The herein-described heating attachment for stoves, comprising a lower section closed at its bottom and having an outer flange at its top edge, strips deflected intermediate of their longitudinal edges and secured tothe inner side of the said section and forming ducts, and the upper section fitted by a slip-joint to the lower section and having indentations to receive the upper ends of the aforesaid ducts and constituting inlets therefor, substantially as set forth.

In testimony whereof I alix my signature in presence of two witnesses.
